Metal lath



Nov. 12, 1935. c. H. SCAMMELL 'MET-AL LATH I Filed Jan. 16, 1955 Patented Nov. 12, 1935 METAL LATH Charles H. Scammell, Forest Hills, N. Y., assignor to Charles H. Scammell Company, New York, N. Y., a corporation of New York Application January 16, 1935, Serial No. 1,993

Claims.

This invention relates particularly to metal lath of that type in which sheets of expanded or perforated metal or wire netting carry a backing sheet against which plaster or other plastic material 5 may be molded and the desired clench of the plaster secure amount of plas d with a comparatively small ter. The invention includes, also,

constructions in which backing sheets are used on both sides or other purposes.

of metallic lathing for shielding Such metal lath in different forms forms the subject matter of my Patents Nos. 1,210,849, 1,499,408, and 1,569,144.

The object of the invention is to provide an improved metal lath in which the metallic lathing shall be provided on one or both sides with a transparent and water-proof sheet, so that no additional layer of water-proof material is ie quired and the lathing may be quickly and conveniently positioned in use, the studs or other members to which the lath is to be attached being visible through the transparent sheet or sheets,

50 that no marker on the lath is required.

Transparent and-water-proof materials of different types may be used, but preferably a flexible, transparent, and water-proof sheet of cellulose material will be used, and I have found that the material known in the trade as Cellophane is well adapted for such use, this material having the above qualities, and in addition the quality of not breaking up or cracking on driving nails or staples through the lath for securing it in position.

For a full understanding of the invention, a description of a construction embodying the in- -vention in a pr eferred form, as applied in a lath for holding plaster, will now be given in connection with the accompanying drawing, and the invention then specifically pointed out in the claims.

In the drawing: Figure 1 is a face View of a portion of the backed lath applied to studs or similar furring in a wall construction; and V Figure 2 is a Referring to section on the line 2 of Figure 1. the drawing, the studs iii are seing is covered crete mixture l trate the lath I3 is shown as with the body of plaster or con- 4, this being broken away to illusconstruction. The backing sheet secured to the metallic lathing by adhesive 2, which may be asphalt composition, and conveniently applied by running the metallic lathing over a, roller carrying the adhesive. Other means for securing the backing sheet to the lathing may be used. 5

As shown in the drawing, the studs are visible through the backing sheet, so that no marker is necessary, and the lath may readily and conveniently be secured in position simply by laying the sheets of lath over the studs and stapling the lath to the studs, after which the plaster or other plastic material is applied.

If the invention be applied in connection with sheathing having backing sheets on both sides of the metallic member, the construction is the same and may be secured in position in the same way by attaching means passing through both sheets of lath. In such sheathing lath, the metallic member will not be used to hold plastic composition, but the inner side of the sheathing may be treated in any desired manner.

It will be understood that the lath may be used in connection with widely different building constructions and attached to either wood or metal supports, the transparency of the lath making it 5 excellently adapted for use in connection with metal work, on which attaching members are liable to be irregularly spaced, rendering it difficult. to properly apply and position non-transparent lath.

What is claimed is:

1. A new article of manufacture comprising metallic lathing having secured theretoa backing of transparent and water-proof material.

2. A new article of manufacture comprising metallic lathing formed to anchor plastic material between it and a plane surface in contact with such lathing, and a backing sheet of transparent and water-proof material secured to said lathing. 40

3. A new article of manufacture comprising metallic lathing formed to anchor plastic material between it and a plane surface in contact With such lathing, and a backing sheet of transparent and water-proof material secured to said lathing by adhesive.

4. A new article of manufacture comprising metallic lathing having secured thereto a backing of transparent and water-proof cellulose material, such as Cellophane.

5. A new article of manufacture comprising metallic lathing formed to anchor plastic material between it and a plane surface in contact with such lathing and a flexible, transparent and water-proof backing sheet of cellulose material, such as Cellophane, secured to said lathing.
